Pathogenesis
•• Chronic injury to the liver results in Chronic injury to the liver results in inflammation, necrosis and, eventually, inflammation, necrosis and, eventually, fibrosis. fibrosis.
•• Fibrosis is initiated by activation of the Fibrosis is initiated by activation of the stellate cells.stellate cells.
•• In the space of In the space of DisseDisse, the normal matrix is , the normal matrix is replaced by collagen. replaced by collagen. SubendothelialSubendothelial fibrosis fibrosis leads to loss of the endothelial fenestrations, leads to loss of the endothelial fenestrations, and this impairs liver function.and this impairs liver function.
•• There is accumulating evidence that liver There is accumulating evidence that liver fibrosis is reversible.fibrosis is reversible.
